Ambassage

am'-ba-saj (presbeia, "an embassy," a body of ambassadors on the message entrusted to them):

Twice used by Christ

(1) in the parable of the Pounds, of the citizens who hated the nobleman and sent an ambassage, refusing to have him reign over them, thus illustrating those who willfully rejected His own spiritual sovereignty and kingdom (Luke 19:14);

(2) of a weak king who sends to a stronger an ambassage to ask conditions of peace (Luke 14:32). Not used elsewhere in the Bible.
